WILLIAM MOOUBBIN, OF OHEATHAM, ONTARIO, CANADA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 372,163, dated October25, 1887.

Application filed March 12, 1887.

To all whom it may concern.-

Be it known that 1, WILLIAM McCUBBIN, a resident of Oheatham, in theProvince of Ontario and Dominion of Canada, have invented certain newand useful Improvements in Car- Oouplings; and I do hereby declare thatthe following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being bad to the accompanying drawings,which form a part of this specification, and in which Figure l is aperspective view of my improved. car-coupling, showing the same coupled;and Fig. 2 is a longitudinal horizontal sectional view taken on line wm, Fig. 1.

' My invention has relation to car-couplings; and it consists in theimproved construction and combination of parts of the same, as will behereinafter more fully described and claimed.

Like letters'of reference denote corresponding parts in both thefigures.

In the accompanying drawings, the letterA indicates my improveddraw-bar, having a hooked forward end, B, provided with a verticalaperture, 0, and a transverse slot, D, its intermediate portion beingformed with a shoulder or abutment, E, and the rear end of the saiddraw-bar is slightly rounded or cut away, as shown at F, and is hingedto the springactuated block G by means of the eye H, fitting into arecess, T, in the end of the same, and the pin I retaining it therein. Aspring, J, is secured to the sliding block and bears with its free endagainst the forward por tion of the drawbar. Thev spring is preferablyconstructed with its rear portion doubled, as seen at K; but anyother'well-known con- SLIIIOIIOIIIIIHJY be employed without departingfrom the spirit of my invention.

It will be seen that by having the rear end of the draw-bar slightlyrounded or cut away a sufficient amount of lateral play is allowed it,and it also enables the wedge-shaped surfaces of the draw-bars to slippast each other, and the springs at the rear of each serve to keep themin engagement when once connected.

A lever, L, is pivotally secured at its lower Serial No. 230,615. (Nomodel.)

end to the draw-bar, having its fulcrum at M, and is adapted to be movedwith its upper end in a guide, N, secured to the end of the car, thesaid guide being provided with a hook or offset, 0. Secured in suitablebearings below the guide N, and slightly to one side of the same, is agrooved pulley, P. A rope or chain, Q, is attached to the lever andpasses through an eyebolt, R, thence around the pulley, and through asecond eyebolt, S. Now, when it is desired to uncouple the cars, it mayeither be done by a person on the top of the car by means of the lever,or on the ground by means of the rope or chain, as it is only necessaryto force the lever toward the hook portion of the guide, thus throwingthe hooked draw-heads out of engagement with each other.

Should it be desired to couple a car provided with my improved draw-barto a car employing the old style link-and-pin coupler, the

link is inserted into the transverse slot in the head of the draw-barand held in place by means of a pin passed through the aperture in thetop of the said draw-bar.

The guide N, provided with the hook or offset O, is for the purpose ofsecuring the upper end of the lever, as shown in" dotted-lines in Fig.1, and while in this position the draw-bar is prevented from coupling,as is often desirable.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States The combination, in a device foruncoupling cars, of a pivoted lever, a guide provided with a hook oroffset, a grooved pulley having its bearings upon the end of the car,and a rope or chain connected to said lever and passed around the.pulley, and thence through an eyebolt, witha movable draw-bar, as andfor the purpose shown and described.

In testimony that I claim the foregoing as my own I have hereuntoafiixed my signature in presence of two witnesses.

WILLIAM McOUBBIN. Witnesses:
